Can't adjust brightness, particularly with Fn keys.
« on: June 20, 2018, 09:21:05 pm »
My laptop F1 thru F12 don't all work. While holding the Fn Key and pressing the appropriate key the screen control keys don't work, but the dim/bright keys do show the box with increasing/decreasing brightness bar, without affecting brightness or turning off the display. I can't adjust the screen brightness at all with the bright -/+ via the battery icon or via Peppermint settings either for the difference that may make. The internal/external key also does not work. The rest as indicated below do work:

Fn 1  Sleep                  Works

Fn 2  Airplane Mode            Works

Fn 3  Keyboard Backlight -              Works

Fn 4  Keyboard Backlight +      Works

Fn 5  Screen Dim                    Not

Fn 6  Screen Bright            Not

Fn 7  Screen Off                    Not

Fn 8  Internal/External Monitor   Not

Fn 9  Touchpad Disable/Enable   Not

Fn 10 Mute                  Works

Fn 11 Audio -                       Works

Fn 12 Audio +                       Works

Searching these forums has not led to finding this issue in particular. What might I do to get this working?         

Note: They all seem to work fine with a multiboot Linux Mint 18.3 KDE install on this same laptop.

Well, it seems the issue persists as noted above, except it is with Peppermint 9 instead of PM 8 respin. I have a new inxi:

I can use xrandr to reduce brightness, but I must apply at each boot, and would prefer settings to retain brightness across boots and be easily adjusted.

Thanks for any replies!

Does the brightness slider work when you right-click on the power manager icon in the system tray (by the clock) ?

You know, I am not sure it is even there, I am not home now to look, but I will look in an hour or two and reply again.

Thanks for the time to assist!

Okay, I do not see a brightness slider. I believe you mean via the battery icon when you right click? When I right click the battery icon I see:

Asustek Asus battery (my laptop)
Anywhere MX (my mouse)
Presentation mode
Power manager settings

In the Xfce power manager's 4 tabs I do not see a brightness slider at all. I do not see the brightness adjust bar at all as I did with no apparent response via PM 8 Respin as I had indicated in my first post in this thread.

Any more suggestions?

P.S. I see the battery icon is the Power Manager via the add new items to the panel.
